摘　　要： 振动过大是引起机车牵引变流器控制箱故障率高的主要原因之一。某型机车部分线路测试表明牵引变流器控制箱振动较大,超过了GB/T 21563—2008的要求。针对现场测试结果,提出了两种控制箱减振方案,通过仿真分析和装车对比试验证明了减振方案具有较好的减振效果和可行性。相关的结论为了解控制箱的振动情况提供了依据,对控制箱的减振工作有重要的参考价值。 Large vibration is one of the main reasons of high failure rate of traction converter control cabinet for locomotive. The partial on-line test results of a locomotive show that the vibration of traction converter control cabinet is bigger than the standard values of GB/T 21563-2008, Two vibration reduction schemes are proposed for the control cabinet. The results of simulation analysis and comparison test on locomotive show that the vibration reduction schemes have a good damping effect and feasibility. Relevant conclusions provide a foundation to understand the vibration of control cabinet, and will be useful to the vibration reduction work of control cabinet.
